Resumen
Se presentan los resultados de investigaciones sobre la actividad foto-oxidativa de sólidos sensibilizados con diferentes compuestos de coordinación. Estos materiales se han empleado en procesos de oxidación selectiva y de oxidación avanzada. La sensibilización del TiO2 con complejos del tipo MoVI(O)2 (L)4 facilita el proceso de transferencia del oxígeno molecular a sustratos como la PPh3 y ciclohexeno bajo iluminación. La sensibilización con ftalocianinas metálicas (TSPcM/TiO2) donde M = Co, Ni, Cu y Zn muestra una sinergia que se evidencia por un aumento en la velocidad de reacción de oxidación del ciclohexeno en medio orgánico independiente del metal central. La presencia de depósitos de platino en el TiO2 sensibilizado con carboxiftalocianinas presenta un incremento en la foto-oxidación del fenol en medio acuoso, bajo irradiación con luz visible. La oxidación de mercaptanos con ftalocianinas intercaladas en sólidos básicos (Hidrotalcita y zeolitas) es posible en ausencia de un medio alcalino externo y bajo iluminación se generan productos de oxidación avanzada.
